To all whom it may concern.

Be it known that I, FRANK A. MCGUIRE, a citizen of the United States, and a resident of Iola, in the county of Allen and State of Kansas, have invented an Improvement in J ournal-Boxes, of which the following is a specification.

This invention relates to an improvement in car journal boxes, and more particularly to an improved arrangement for providing an auxiliary oil supply for the journals.

One of the principal objects of the invention is. to provide a journal hox having an auxiliary oil reservoir or cup therein adapted at a predetermined temperature to discharge its contents into the box for lubri eating the axle journal.

Another object of the invention is to provide a car journal box with an auxiliary cup having a fusible plug or stopper for maintaining oil within the cup, the stopper adapted to melt at a predetermined temperature for allowing escape of the oil into the journal box, means being provided in the form of a signal for advising the train. men when the cup is emptied.

Still a further object is to provide a device of the class described which will beextremely simple, durable, efficient in operation, and inexpensive to manufacture.

With these and other objects in view which will become apparent as the description proceeds, the invention resides in the construction, combination and arrangement of parts, hereinafter more fully described and claimed, and illustrated in the accompanying drawing, in which like characters of reference indicate like parts throughout the several figures, of which Figure 1 represents a top plan view of a journal box provided with the improved auxiliary oil cup. Fig. 2 represents a view in section taken vertically and longitudinally through the journal box and cup, and Fig. 3 represents a view similar to Fig. 2 showing the cup as applied to a different form of box lid, or cover.

Referring more particularly to the drawing, a car wheel is indicated at 5 and the axle journalv at 6.

A journal box 7 of usual construction is provided for lubrication of the axle journal and as usual is provided with a supply of cotton waste 8 which is saturated with the lubricating oil indicated at 9.

In Figs. 1 and 2 I have shown the journal bQX as being provided with a horizontally extendlng cover 10 hingedly connected to the box at its rear edge at 11 and provided provided on the front wall of the journal box for maintaining the cover in closed positlqnj The lid 10 serves to carry the auxiliary or emergency oil cup 17. This cup is substantiallv in the form of a funnel, and at its lower end is closed by a stopper 18. The stopper is made of some fusible material which is adapted to melt at a predetermined temperature. Thefusing point of the stopper will be substantially equal to, or slightly above, the temperature created when the oil in the cotton waste 8 becomes exhausted, or some temperature below the ignition tempera llre of the waste.

D'sposed 'n cup 17 above its lower end is a spider 19 provided with a central opening through which a rod 20 slidably extends.

The lower end of the rod is provided with an eye 21 to prevent the upward detachment of the rod from the spider. At its upper end the rod extends through an opening 22 provided in the lid 10 of the journal box,

this rod when the stopper 18 is in position, extends somewhat above the lid and is provided with an eye 23. The latter prevents downward displacement of the rod through the lid 10. An opening 2a in the box lidserves as means whereby oil may be poured into the cup 17 above the fusible I stopper 18. A closure 25 of suitable form i provided for the opening 2e.

When the stopper is in place the rod 20 at its lower end bears against, and is maintained in raised position through the medium of, the stopper. The oil inthe cup 17 is retained therein until the oil in the waste 8 having been exhausted and the temperature of the journal having risen above normal or to the fusing point of the stopper 18, the latter melts and the oil contained in cup 17 is discharged by gravity into the box and saturates the waste so that the axle journal is properly lubrioatediand the waste is prevented from igniting- Upon melting of the stopper the shaft 20 will drop until only the upper eye 28 remains above the surface of the lid 10, so that a signal will be thus giigen to the trainmen that the cup is emptie In Fig. 3 the journal box 7 is shown as provided with an inclined lid 10, instead of With a horizontal lid. The cup 17 is se cured to and depends from lid 10 in a vertical manner as shown and is provided with a stopper, spider and rod, and filling means similar to the corresponding parts already described in connection withthe cup carried by the horizontal lid. The operation of the cup carried by the inclined lid is exactly the same as that already described.

It may be preferable to use the horizontal lids, for the reason that a larger cup may be accommodated than can be accommodated by the inclined lids. If desired the inclined lids may not be thrown away but they may have the sides 13 and front walls 12 brazed to them to support them in horizontal position and provide a closure for the journal box. Or, if found desirable, the horizontal lids may be manufactured initially with the side and front walls provided thereon.

Such a device as I have provided will prevent the occurrence of hot boxes in the car journals, and will obviate any guess work on the part of the trainmen as to When the auxiliary cups are emptied.

Although I have described the preferred embodiment of my invention, I may desire to make such changes in the construction, combination and arrangement of parts thereof as do not depart from the spirit of the invention and the scope of the appended claims.

I claim 1. The combination with a ournal box of a lid, a cup depending from the lid and being open at its lower end, said lid within the compass of the cup being provided with a filler opening, a stopper disposed in the lower open end of the cup and adapted to fuse at a predetermined temperature, a spider disposed within the cup and being provided with an opening, a rod slidably extending through the opening in the spider and bearing at its lower end against said stopper, said rod at its lower end being provided with an eye, said rod also extending through an opening in the lid and projecting above the same when the stopper is in place, the upper end of the'rod being provided with an eye, said rod when the stopper is melted being adapted to drop whereby to provide a signal, substantially as described.

2. The .combination with a journal box having a lid, of a cup depending from said lid and being open at its lower end and adapted to receive oil, a fusible stopper disposed in the lower end of the cup for closing the same whereby to retain the oil within the cup, a spider arranged in the cup, a rod slidably extending through the spider and through the lid of the box and resting against said stopper, substantially as described.

3. The combination with a journal box, of an oil reservoir disposed therein and having a fusible closure, and a signal supported by the closure and adapted to be actuated upon fusion of said closure.

hThe combination with a journal box having a lid, of a cup depending from the lid and provided With a fusible stopper adapted to maintain oil within the cup except at a predetermined temperature, and a rod visible from without the box and resting against the stopper, said stopper adapted to melt at a predetermined temperature whereby to allow the discharge of oil from the cup into the box, and to allow shifting movement of the rod.
